Network Utilization

So i purchased a crossover cat 6 cable to connect my MBP to my pc, for all my files are on the pc, and i wanted to put them on my MBP. Now when i set up sharing and all that good stuff, and open my MB's folders on my pc and drag and drop the files to the mac, i only get 20-30% utilization, and mid way during a large transfer, i drop to .1%, then it kicks back up to 20-30%. Why don't i get full usage for they are both gigabit Ethernet, and i have a cat 6 connected at 1gbit/sec.
Thanks

Hi silbeej,
In this case, your speed is being limited by how fast the drives and read and write. The rated sustained write speed for the drive in my macbook pro is 44Mbyte/sec, or about 352Mbps, or about 30% utilisation for gigabit ethernet...
So, yes, this all looks about right.

Low Network Utilization in Remote Disk Backup via SAP FTP

Hi gurus,
I'm running whole online backup + redo log to backup my SAP server to backup server via SAPFTP (remote disk backup).
I'm using 100Mbps network connection between the two servers, with SAP server configured to 'maximize data throughput for network application'.
When I copy data from SAP Server to backup server manually, the speed is OK (around 98% network utilization).
But when I use put command in program RSFTP002 (SAPFTP) for the same file, the network utilization is just around 10%.
I use Windows Server 2003 x64 for SAP Server, and Windows Server 2008 x64 for Backup Server.
Each has adequate RAM, 8GB for SAP Server and 4GB for Backup Server.
Is this technical problem or is it because backup is considered background process, thus lowering its speed?
Help will be very much appreciated.

go read http://help.sap.com/saphelp_45b/helpdata/en/0d/d311324a0c11d182b80000e829fbfe/frameset.htm
it's old but should help you nonetheless.
I would not use SAPFTP as you found out, it is slow.
use DD instead which is much faster.

Network Utilization script throws error after re-executing

Hi everyone, I have a piece of code that finds the network util of a fileserver and if it is over 75% it stops executing the script. The script works the first time but after re-executing it, it throws an error. I've tried to null out all the variables I'm
using but it still won't work. Any help is appreciated! Thanks!

Wrt310n gigabit ethernet 20% network utilization?

hi there,
I am transfering a large multi-gigabyte file over the gigabit ethernet of the router, two computers, which both register as 1 gbps in the network window of the Task Manager and I see the network utilization is only about 20%.
Should this network utilization not be higher (these are the only two computers that are transferring any significant data.
thx,
Cos

As long as you have Internet Connection up and running you should not worry about the Network Utilization...
You should use CAT 6e cabling on a Gigabit connection...

High Network Utilization among NLB Node in Server 2012 R2 NLB

Hi Team,
I have configured the server 2012 R2 NLB with 3 NLB node to
load balance. WFE1 (192.168.1.4, public IP 182.73.208.4) , WFE2 (192.168.1.5, public IP 182.73.208.5) , WFE3 (192.168.1.6, public IP 182.73.208.6). On putting load on WFE1 public IP we have noticed that the ping requests to the three nodes time out very frequently
(Network Utilization seems very high) even when the network utilization for WFE1 server is around 30%. When the WFE1 server is not a part of NLB, and after putting load, the ping requests rarely fail even though the Network utilization on WFE1 server goes
up to 70% or higher.<o:p></o:p>
All the NLB node is hosted on 3 different hyper-v host.....can anyone suggest any solution..<o:p></o:p>
Shailendra Dev

Hi,
When you use the Hyper-V guest vm as NLB cluster node, you need to enable the spoofing of MAC address, pleae reconfirm you hae enable this option.

Wireless Network Utilization

Relatively simple question, I am just having a tough time figuring out analyze the data.
Anyway...
We use the Tamograph Wireless Survey utility and with this utility you are able to perform passive, predictive and active surveys.
With the passive\predictive you can calculate the SIR (Signal to Interference ratio) expected. You can change the "average network utilization" as a variable to formulate the SIR values.
I am having a tough time correlating our controller\AP data with that value.
When I look at the AP's I see Load Statistics. Would I be concerned with TX, RX or Channel Utilization or ALL when it comes to 802.11 interference ratios?

From the application support documentation:
"This visualization shows the signal-to-interference ratio (SIR) measured in dB. SIR is a measure to quantify by how much the signal level of an AP (interfered AP) exceeds the interference level. The interfering signal is the signal being transmitted by other APs (interfering APs) that may or may not belong to your WLAN and that use the same or one of the adjacent 802.11 channels. In low SIR zones, client devices may experience low throughput. SIR is shown for the AP that experiences the worst interference in the given map area among the APs selected for analysis. You can deselect one or several of the selected APs to see SIR values for the APs that experience less interference."
"SIR is best illustrated with an example. Consider an area where the AP signal strength is -50 dBm, and the AP works on channel 1. In the same area, a -70 dBm signal from another AP that works on the same channel can be seen. If WLAN utilization is 100% (i.e., if the APs send radio waves all the time), the SIR value would be 20 dB. However, real-world WLAN utilization is almost never that high, which decreases the interference and increases SIR. If the interfered and interfering APs have the same signal strength, the SIR value would be 0 dB. In classical, non-digital radios, a SIR value of 0 dB makes signal reception impossible, but 802.11 devices use a technology that allows them to operate despite a zero or even negative SIR value, which sounds counterintuitive."
On network Utilization -
"Average network utilization – This setting defines how heavy the interference is from the interfering APs. If the interfering signal strength is high, but the network utilization is low, the interfering AP does not create much interference. A typical office WLAN has a network utilization of between 10% and 25%. Adjust this setting to match the actual value for your WLAN. "
After reading all of this would you say that Channel utilization is the best value to look at on the Cisco WLC that correlates to the "Average Network Utilization"?
I am going to check with the software vendor as well. In the meantime what is a good, expected Channel utilization value? Is there a range?

How to fetch network utilization...

I am doing a project related to network monitoring
so i need to know the the utilization of network
resource,
we can say the incoming and outgoing traffic of a
particular network interface card, or the percentage
utilization of the capablity of that network card..
Is there any API related to that..so i can use that...
i shall be really thankfull

If the devices in question have SNMP agents running, you could find an SNMP library and query the appropriate OIDs.
Whatever approach you take will involve a fair amount of research and work. There's no getUtilization(host, interface) method in the core API. You might be able to find a 3rd party library, but that would defeat the purpose of your homework.

8.1 system process spiking cpu, disk, and network utilization.

Hi all,
After the most recent update to 8.1(I believe it was Mon 5/19/2014,) my laptop has been giving control to another program for about half a second, and then returning it to me. If I am typing, nothing comes up during that
moment, the menu bar changes visually, then it quickly reverts. This is more annoying than malicious. After some digging I found that cpu, disk, and network all spike at the same time, about 5 seconds apart. Here's what I've gathered:
Task Manager: Under the process tab, Windows Problem Reporting,(under background processes), pops in and out when the problem occurs. This is EXTREMELY odd as I've disabled the Windows Error Reporting service. Under the performance tab, The spikes are all
concurrent and similar in appearance, as shown on the graphs.
Services: When I *stop* the Windows Error Reporting service I get: "Windows could not stop the Windows Error Reporting service on local computer. The service did not return an error. This could be an internal
Windows error or an internal service error. If the problem persists, contact your system administrator." So I have *disabled* it.
Resource Monitor: I find multiple instances of WerFault.exe using different pids. They are under network activity and tcp connections, all pointed at 157.56.141.101. A quick look-up revealed that this address is registered to Microsoft.
Wireshark: My machine is initiating a TCP 3-way handshake to the above mentioned IP address, originating from random port 50379 and destined for port 443. Using TLSv1.2, I see a key and cipher change, an encrypted handshake, and then appliction data being
transferred. The conversation ends with a 3-way goodbye, BUT immediately after the fin ack, my machine sends a rst ack and the conversation begins again. Ad nauseam.
Any info or help would be greatly appreciated. I feel like my machine has the literal hiccups. I've run Avast and MalwareBytes to eliminate malicious software. Both came up clean. I have no issues detected
in Action Center. The most recent thing I've done was install HP drivers for my PhotoSmart D110a. I have uninstalled both the drivers and software from HP. To be honest, I am completely over Windows 8. I feel like I've had nothing but problems with it. Way
too much going on with it. I'd rather have few features that work, than a million that are sub par in every sense of the phrase. End rant. If you need any more data or information from my end, please let me know. Will be more than happy to help you help me.
Thanks in advance for your time.

p.s. I had to delete the screenshots due to my account not being verified and I can't figure out how to verify being that it doesn't ask for my email. In doing so, the text has been resized. Apologies in full.

I figured it out. I didn't look in event viewer. The issue was Asus Smart Gesture was crashing and restarting and then crashing again. This caused Error reporting to constantly send the issue. I entered the asus folder, ran the uninstall.bat, and re-installed
it. Solved it immediately.

K8N Neo3 nForce 4-4X doesn't show network utilization for some reason

Has anyone had this problem? If I am downloading something and I check the Windows Task Manager the networking tab shows no activity for some reason. I figure this is probably a known problem, but I haven't seen anything on it yet.

Large network utilization leads to weird things

Arch linux works fine for a couple of days of uptime as my desktop. After a few days (there's no set amount of time), I'll start a large file transfer over NFS to my NAS. In the middle of this transfer my connection will randomly die.
"ip addr" shows eth0 has lost its network address.
"dhcpcd eth0" fails to renew the address.
Manually setting the address to its original value does not restore connectivity.
Furthermore, when I try to "reboot" or "poweroff" the system, the command stalls and no services are shut down.
I'm at a bit of a loss on how to troubleshoot this issue.

Hi,
I don’t found your server hardware model supported by Server 2012R2, you may can ask your server vendor for the future assistance, personal experience is most of the server
must enable the SR-IOV in BIOS, or must update the BIOS to the support version.

High Network Utilization on HeartBeat and LiveMigration networks - Windows 2012 R2 Hyper-V cluster

Hi all,
I have just setup a fresh Windows 2012 R2 Hyper-V cluster with 4 nodes.
Config:
Network:
2 x Networks for iSCSI
1 x VM network 1
1 x VM network 2
1 x Heartbeat
1 x LiveMigration
Disks:
5 GB = Quorum
2 x 2.99 TB (Deduplication enabled)
The problem I am getting is that HeartBeat and LiveMigration (both configured with Cluster Only traffic) have alot of traffic on them even though no LiveMigration (the only card configured for LiveMigration) is going on.
All network configuration is the same as it was in Windows 2008 R2 SP1 cluster which these machines where running before (not upgrade, fresh install and migration) and did not have this "problem".
Has anyone experienced this or have a solution to this?
Regards,
Thorir

Network Utilization Lower Than Expected

We are imaging systems using PXE and have 8 of them going at the same time. We looked on the server and it had like 200 mbps usage. I would expect it to be much higher (we have 2 - 1 gig nics on the server).
Is there something that throttles this? Any thoughts?

Create this in registry on Your PXE WDS Server:
HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\DP\RamDiskTFTPBlockSize
Type Reg_Dword
Value: 16384 Dec (Do not use higher value than this!)
((Recommend that you increase this setting in multiples (4096, 8192, 16384, and so on) and that you not set a value higher than 16384.))

Poor network performance Pavilion 500

Has anyone ran into and solved an ethernet performance issue on the HP Pavillion 500 (500-047cb) where the nic is unable to acheive speeds of 20MB/sec or higher? The max download performance of my current card is in 5MB range.
The same computer gets 16MB/sec (downloads) running wifi. Other computers on the same network get more than 25MB/sec. Maybe its a driver or OS related issue because the last speed test had a download speed that was lower than the upload speed. Any ideas?

Hello @pops10009,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that you are not getting the speed out of your wireless that you should on your HP computer. There could be an issue with your Wifi Adapter. I could be corrupt or not as update to date as it should. To ensure this is not the case follow the steps below:
These steps are for computers running Windows 8 or Windows 8.1.
First we need to determine what your product number is. You can do this by following the HP Support document that pertains to your computer type
Notebook - How Do I Find My Model Number or Product Number?
All-In-One - How Do I Find My Model Number or Product Number?
Desktop - How Do I Find My Model Number or Product Number?
Once you have your product number you can use it at HP's Drivers & Downloads page. You should see your computer listed click on it and you will be brought to your computer's drivers page. Select your operating system from the drop-down box. If you are unsure as to what operating system you are running or what version it is you can use Which Windows operating system am I running? to determine what your operating system is and Is the Windows Version on My Computer 32-bit or 64-bit? to determine what version the operating system is. Once you have your operating system selected click 'Next' and scroll down you will see Driver - Network. Click on Driver - Network and you will see your Wireless driver. Download and save it to your Desktop or a location you will remember on your computer.
Now that you have your wireless driver downloaded follow the instructions I have set out below:
Step 1. At the Tiles Menu type "device manager"
Step 2. Click on Device Manager
Step 3. Click on Network Adapters
Step 4. Right-click on your Wireless Adapter and select Uninstall
***Ensure you delete the driver when the option is presented
Step 5. Go to the wireless drivers you downloaded earlier and install them
Step 6. Restart your computer
Next we are going to check to see what is using your internet. There are a variety of applications that will connect themselves to your internet slowing you down without notifying you. There is a simple way of seeing what applications are connected slowing you down. To do this follow the instructions below:
Step 1. At the Tiles Menu type "command prompt"
Step 2. Right-click on Command Prompt
Step 3. Click on "Run as administrator"
Step 4. Type "netstat –b 5 > activity.txt" and hit Enter
***Be patient while the computer creates a file on your computer
Step 5. Close down the Command Prompt
Step 6. At the Tiles Menu type "activity.txt"
Step 7. Click on activity.txt
Step 7. Review activity.txt thoroughly
Step 8. If you see applications that do not need to be running you can close them down.
If you do not know how to close out applications running in Windows 8 follow the instructions I have set out below:
Step 1. Press Alt+Tab simultaneously and hold them down
***A window will pop up with all the apps, and their icons, that are running on your PC.
Step 2. Guide your mouse over the icons
Step 3. Right click on the icon representing the application you wish to close
Step 4. Click “Close”
Next we are going to look for Processes that are using your internet that may be slowing you down. Once again follow the steps I have set out below:
Step 1. Right click your Taskbar
Step 2. Click Start Task Manager
Step 3. Click on the Networking tab
*** Processes consuming internet speed are shown here
Step 4. Under the Network Utilization column you will see processes with a higher percentage of network usage
*** Processes you do not need can be closed by looking them up in the Processes tab
Step 5. Select the process in the Process Tab you wish to close
Step 6. Click End Process
Next we are going to clear the cache, cookies and browser history. I have again set out some steps below to follow:
Step 1. At the Tiles Menu type "internet options"
Step 2. Click on Internet Options
Step 3. On General tab click the Browsing history section
Step 4. Click Settings
Step 5. On Temporary Internet Files tab of Website Data Settings window, type 0 as Disk space to use
Step 6. Click to the History tab, and specify a minimum number of days to keep pages in history
Step 7. Click on Caches and databases tab, uncheck Allow website caches and databases
***You can also reduce the cache file size in MBs to notify yourself
Next is a nifty feature where by default your system will wait for your data packets will fill up and then send them over your network this is called the Nagle-Algorithim and it can be disabled by following the steps below:
Step 1. Back up your registry by following the HP Support document: Backing Up, Editing, and Restoring the Windows Registry (Windows 8)
Step 2. At the Tiles Menu type "registry editor"
Step 3. Click on Registry Editor
Step 4. on the left pane expand your way through HKEY_LOCAL_MACHINE until you locate "SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces"
Step 5. Right-click the empty place
Step 6. Click New to create two DWORD Values
Step 7. Rename these values as ‘TcpAckFrequency’ and ‘TCPNoDelay’
Step 8. Double-click both the entries to Modify
Step 9. Put 1 as their Value data to activate them
Step 10 Click OK to save your changes
Step 10. Close Registry Editor
Step 11. Restart your Computer
Next we are going to clear/flush your DNS cache. You can do this by follow once again the steps I have set out below:
Step 1. At the Tiles Menu type "command prompt"
Step 2. Click on "Run as administrator"
Step 3. Type "ipconfig /flushdns" and hit Enter
***You will know you are successful if you see a message stating “successfully flushed the DNS Resolver Cache.”
The next thing we are going to do is disable global auto-tuning as if this is not working correctly you can experience slow internet speeds. To disable the global auto-tuning follow the steps below:
Global Auto-Tuning is related with the data transfer for HTTP traffics. You might be experiencing slowed Wi-Fi internet problem if the Auto-Tuning feature is not working properly. Simply disable it as follows:
Step 1. At the Tiles Menu type "command prompt"
Step 2. Right-click on Command Prompt
Step 3. Click on "Run as administrator"
Step 4. Type " cd C:\Windows\System32 netsh interface tcp set global autotuning=disabled" and hit Enter
Step 5. Type "netsh interface tcp show global" and hit Enter
***Does it show Auto-Tuning is disabled? If yes, you have performed everything properly. Otherwise, you need to check-out the commands you have written and try again.
Another part of Windows that can make your WiFi slow is the remote differential compression api. the remote differential compression api is is a client–server synchronization algorithm that allows the contents of two files to be synchronized by communicating only the differences between them. To uninstall this as it is not needed simply follow the steps below:
Step 1. At the Tiles Menu type "programs and features"
Step 2. Click on Programs and Features
Step 3. Click Turn Windows Features On or Off under Programs and Features
Step 4. Uncheck the box named Remote Differential Compression API Support
Step 5. Click OK
The final set that you can do is ONLY AVAILABLE ON WINDOWS 8 PROFESSIONAL AND WINDOWS 8 ULTIMATE EDITIONS as it requires the Local Group Policy Editor. What this steps does is alter the reservable bandwith in Windows 8. What this does is reserve bandwidth for multiple users and so there is bandwidth set aside that is not being used and can be. Additionally the packet scheduler reserves 20% of yoru bandwith by default even if it is disabled. This can be reduced to 0 by following the steps below:
Step 1. At the Tiles Menu type " gpedit.msc"
Step 2. Right click the search result and choose to Run as administrator
Step 3. Click on the QoS Packet Scheduler
Step 4. Navigate to Computer Configuration \ Administrative Templates \ Network \ QoS Packet Scheduler
Step 5. Double click Limit Reservable Bandwidth
Step 6. Click to Enable it
Step 7. In the Options section next to Bandwidth limit (%) reduce the number to 0
Step 8. Click OK
Step 9. Close down Local Group Policy Editor
If you have followed the steps I have set out in this post your internet speed in Windows 8 should have improved. Thank you for your time and have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!
Also be sure to mark my post as “Accept as Solution" if you feel my post solved your issue, it will help others who face the same challenge find the same solution.

Windows Deployment Service. Network Profile Radio Buttons greyed out with R2

Hi All
I have downloaded and setup Server 2008 R2 (not yet activated). I have added the following roles "DHCP Server", "DNS Server", "Active Directory Domain Services" and "Windows Deployment Services". I can PXE boot a test client machine and (using the boot.win from windows 7 dvd) multicast a XP Image to it. This setup is connected via a 100 Mb switch and is an isolated network.
Under windows deployment services - if I right click my server - select properties - network tab "Network Profile is greyed out". I have tried running wdsutil /Set-TransportServer /Server:big /Profile:100Mbps but get the following error message: "Windows Deployment Services Management Utility Version 6.1.7600.16385. Error code 0xC110011F This WDS transport server does not support network profiles.
I have tried this on two hardware setups:
An Intel D915GUX 3GHz 2GB RAM and Marvel Yukon 88E8050 ethernet controller.
An Intel D965 Core2Duo 1.86GHz 2GB RAM and Intel 82566DM Network controller.
Incidently I have done the same setup with Server 2008 (not R2) on the D965 and the Network Profile radio buttons are not greyed out. If I upgrade the same test machine to server 2008 R2 the Network Profile radio buttons are greyed out. Is this a design change, does Server 2008 R2 no longer support network profiles as I am now unable to select 10 100 or 1000 Mbs ?
If more information is required or if anything needs further detail please let me know.
Thanks for any help.

Is there any way at all to manually set or control the network profile? In my environment, a SCCM\WDS multicast stream is bottoming out on speed and network utilization when the stream crosses a Nexus 7009 router. Speeds go from 200 Mbps to 20 mbps. I have
a theory that this "new" automatic configuration is placing the clients in a slow network profile that are on the opposite side of the router and I have been unable to find a way to speed of the transmission. I have also ruled out the "master
client" slowing down the stream buy using different clients only connecting to a stream 1 at a time. I have also ruled out the router as the source of the problem by having a VLC client listen to the multicast stream on the same side of the router as
the slow clients. The VLC client (unknown to SCCM\WDS) was able to receive the transmissions at 20 % utilization / 200 Mbps.

Curious about App-V 4.6 RO Cache Network Traffic

Our environment is Server 4.5 SP2, and Client 4.6 SP3. We utilize RO cache on DFS network storage, and our clients are VDI VM's.
We recently ran into an issue when we recycled a large pool of VM's where the CPU/Network Utilization was maxed on our cache file server. Upon further investigation there appears to be about 550MB of traffic between each VM and the Cache file itself when
the VM boots (no users logged in). Can someone explain to me what this traffic could be?

In RO cache mode (ReadOnlyFSD], *nothing* should get streamed down to the client at all.
where does the amount of data show up - any specific files/folders, or monitored network traffic between the client and the DFS share?
is there anything in the App-V log file?
Did you initiate a server publishing refresh with a user that has access to all applications before you sealed the VDI Master image?
